Embodiments of the present disclosure provide a method and device for establishing backup path, a method and device for selecting backup path. The method comprises a first node in a first IGP domain receiving a response message of successful establishment of a main path from a second node in a second IGP domain through the main path; the first node obtains path information of the main path from the response message; the path information of the main path includes at least SRLG information of a link composing the main path; the first node establishes, according to the path information of the main path, a backup path between the first node and the second node; the SRLG information of a link composing the backup path is different from the SRLG information of the link composing the main path.

The invention belongs to the technical field of shield tunnel construction project and in particular relates to a grid reinforcing method of a shield receiving or starting end head and a shield receiving method. The invention aims at the risk source of starting and receiving shield. In the grid reinforcing method of a shield receiving or starting end head, the shield receiving or starting end head is provided with a grid waterproof reinforcing element. The invention has the advantages of completely cutting off water source compensation during final reception so that a shield machine carries out reception and starting under the geological conditions without water, fundamentally changes the original geological conditions, and ensures the safety of the shield. Compared with the traditional methods, the method saves more than 30% of cost once, the reinforcement effect thereof is greatly higher than that of the traditional method, the method reduces at least more than 70% of risk rate, hasinestimable benefit and value as subway construction is carried out like a house on fire currently, and has easy operation, inspection and convenient popularization and promotion.

The invention discloses an intelligent environment management system based on the Internet of Things. The system comprises a dust concentration detection module, an oxide detection module, an environment parameter detection module, a noise comparative analysis module, an environment parameter storage database, a particle content analysis module, a data pre-screening processing module, a managementcloud server, an intelligent display terminal and a mobile dust suppression mechanism. According to the invention, whether the dust content and the temperature in the factory reach the explosion danger degree under the combined action can be comprehensively analyzed, and a mode of combining software and hardware is adopted; the mobile dust suppression mechanism is controlled to move to the position of the detection sub-region of which the predicted explosion danger coefficient is greater than a set predicted safety explosion danger coefficient threshold value, so the dust suppression operation is realized, and the explosion risk is reduced; whether the working environment meets the personnel office environment requirements or not can be judged through the statistical working environment matching suppression system, the environmental conditions in the personnel working environment can be visually displayed and analyzed, and the detection accuracy is high.

A method and system for building a safety knowledge graph for smart power plants. This method first collects data and constructs a knowledge model, classifies, cleans, and stores the data according to the knowledge model; then performs knowledge extraction on the unseparated data of the entity, and uses the results of the knowledge extraction and the separated data of the entity to make a knowledge map construction; and finally apply the constructed knowledge graph to different scenarios. The invention also discloses a system utilizing the method. Compared with the prior art, the feature-based knowledge extraction method of the present invention can extract entities more accurately, and can extract relationships more quickly and accurately by encoding entities and sentences and then using CNN. The knowledge map constructed by the present invention comprehensively considers the application status and requirements of safety management in electric power enterprises, can effectively reduce the safety risks in the production process of power plants, facilitate enterprises to realize intelligent management in electric power production, and ensure the production safety of power plants.

The invention discloses an Internet-based automobile charging system, which includes optimized charging equipment, several charging pile terminals, and several vehicle-mounted terminals, and the optimized charging equipment is respectively connected with several charging pile terminals and several vehicle-mounted terminals; the charging pile terminal includes a first processor and a plurality of vehicle-mounted terminals. An output detection module connected to the first processor, a parameter detection module, a storage database and a first communication transmission module; the vehicle-mounted terminal includes a second processor and a vehicle-mounted memory connected to the second processor, an electric power detection module, and a second processor , Connect the paired module and the display terminal. The invention guides the vehicle to the charging area with the shortest cumulative charging time, reduces the time wasted by car owners blindly searching, and improves the charging efficiency and reduces the waiting time through automatic plug-in and position calibration positioning, and combines the temperature, humidity and The cumulative charging time evaluates the danger of the charging pile, which improves the service life and safety of the charging pile.

The present invention provides a photovoltaic module lamination process, including the following process flow: ① providing a photovoltaic module and a laminator for laminating the photovoltaic module, the laminator is provided with a heating plate, and the photovoltaic module There is a self-heating plate on the top; ②Set the lamination parameters on the laminator, and when the temperature of the heating plate and the self-heating plate reaches the specified temperature, put the photovoltaic module into the laminator and close the cover; Vacuuming operation between the layers; ④Then pressurize the upper chamber of the laminator, press the self-heating plate to the top of the photovoltaic module, and the self-heating plate and the heating plate simultaneously The photovoltaic module is heated; ⑤ After lamination, the lower chamber of the laminator is inflated, the upper chamber is evacuated, the upper cover is opened, and the photovoltaic module is taken out, and the lamination is completed. Such setting effectively controls the heating temperature of the photovoltaic modules at different stages, shortens the lamination time of the photovoltaic modules, and improves the production efficiency.
